Annie Nozawa Hi Ruth! Are you trying to decide what color to paint your roof, or your house?

Michelle Mink I assume you are painting the siding. This answer sounds like a cop-out, but it's really not. Either color, slate-blue or green grey, will work with your gray galvanized roof. It's really a matter of preference. Both sound terrific with the white trim you have planned.

Ruth Fagan Thanks for the advice. I am actually looking to paint the weatherboard exterior, the tin roof is a light steel grey and has changed the look of the house which was previously pale green and cream with a dark grey roof.

carolannr Love a grey blue with white trim.

Annie Nozawa Ahh, in that case, I agree with Michelle that both colors would look great, but I am leaning toward painting it steel blue -- that would be so fresh! Would you also paint the cream trim to something more true-white? That would really make the blue stand out! When the job is done, share the "after" -- would love to see it!!

decoenthusiaste Sherwin Williams has a couple of colors that might look pretty; Foggy Day or Glisten Yellow and I'd try Extra White for the trim.
